It is all a matter of orientation. If they take the time to train you properly, teach you what to look out for, how to do an expert assessment and deal with critically ill patients, you may do fine.
If the precepting, mentoring you receive is less than adequate, you'll be setting yourself up for failure.
Getting your bearings on any floor as a new graduate is difficult enough. It's that much more difficult getting your start in critical care.
I'd try to speak to several nurses working in the ICU to get a feel for how new graduates are trained and how much time, energy and patience they devote to new orientees. I'd look for an orientation period of at least six months.
